WASHERLESS FAUGET.

Original application filed July 24, 1912, Serial No. 711,197.

Specification of Letters Patent.

Serial No. 752,016.

To all whom 2'25 may concern Be it known that I, HENRY 0. BROWN, acitizen of the United States, residing in the borough of Brooklyn,county of Kings, State 6 of New York, have invented a new and usefullVasherless Faucet, of which the following is a specification.

This invention relates to a novel construction of a faucet or valve andembodies subject-matter originally disclosed and claimed in my pendingapplication Serial No. 711,197, of which the present application forms adivision.

It has for an object to provide a valve in which no packing or washersare necessary or employed to prevent leakage and which maintains a fluidtight seal with its seat.

It is a further object of my invention to not only provide a valve whichis leak proof but is positively locked in its closed position and as anauxiliary to this locking means I rely upon the pressure of the fluid tofurther insure the valve being retained in fixed position on its seat.

My invention further consists of a novel construction whereby the actionof the valve is such as to prevent particles of dirt from holding thevalve partly open or causing the valve to be scored, whereby it becomesunfit for service or requires grinding.

It further consists of other novel features of construction all as willbe hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in theaccompanying drawing, one form thereof which is at present preferred byme, although it is to be understood that the various instrumentalitiesof which my invention consists can be variously arranged and organizedand that my invention is not limited to the precise arrangement andorganization of these instrumentalities as herein shown and de scribed.

Figure 1 represents a sectional elevation of a faucet embodying myinvention, the

valve being shown in closed position. Fig.

2 represents a sectional elevation similar to Fig. 1 showing the valveand its adjuncts in open position. Fig. 3 represents a section of thevalve stem.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, the valve body or casing is formed in thepresent instance of two body portions or parts designated by thereference numerals 1 and 2, the former of which is provided with athreaded extension 3 for the purpose of connecting the faucet with anydesired source of fluid supply, which as here shown enters the casing 1through the inlet 4:. The opposite end of the casing 1 is provided witha threaded port-ion 5 adapted for engagement with a threaded cap member6 which performs the function of a union head and maintains the parts influid tight engagement with each other.

The casing member 1 in the present instance is provided with a wall orabutment 7 which extends into the enlarged chamber 8 of the casing saidabutment having its inner face 9 curved or inclined in the nature of acam the purpose of which will later appear. The outlet 10 of the faucetis formed in the member 2 and communicates with a passage 11 leading tothe chamber 8.

12 designates an annular member forming a valve seat which encircles thepassage 11 and is suitably secured in the face of the casing member 2 aswill be apparent. This member 12 in the present instance has a drivingfit with the part 2 and it may therefore be readily removed and replacedshould occasion demand.

13 designates the valve which in the present instance is formed with aprojecting cam face 14 which is adapted to contact at certain times withthe facet) of the part 1. The inner face of the valve 13 seats upon themember 12 and is preferably recessed as shown at 15 in order to receivethe. head or plate 16 which is eccentrically connected with or forms apart of the valve spindle 17 and it will be noted that this latter isprovided with a reduced neck 18 which passes through an opening 19 inthe casing member 2, thus forming a shoulder 20 which pre vents thespindle 17 from becoming displaced when operated by the hand wheel orlever 21.

The valve 13 as here shown is loosely mounted on the head 16 in order tofreely rotate and also allow sutlicient clearance so that the pressureof the fluid exerted against the rear portion of the valve will maintainthe same properly seated and prevent leakage. Furthermore, this pressurealso maintains the valve in place upon the head 16 so Cir that when thehand wheel 21 is turned the valve 13 will move from the position seen inFig. 1 into the position shown in Fig. 2 or the open position. When thehand wheel is turned to close the valve, the cam face 14 will bearagainst and ride upon the inclined face 9 so that a wedging action willtake place which. will firmly hold the valve 13 to its seat 12.

An additional advantage in this action will be seen when it isunderstood that the valve 13 in moving toward its seat has a 1'0- tarymotion which tends to bring the contact faces of the valve and the seatinto exact conformity with each other and this action causes anyparticles of dirt or foreign matter in the liquid to either be pushedaside or ground into such a minute condition that it is practicallyimpossible for the valve to become clogged or scored by the presence ofsuch foreign particles.

Special attention is directed to the fact that in my present invention Ihave entirely eliminated the necessity of employing a packing or gasketin order to maintain a fluid tight seal between the valve and its seat,and I am thereby enabled to entirely eliminate the necessity ofcontinuously repacking the valve at frequent intervals, such as isnecessary when the ordinary types of faucets are employed.

It will be apparent that in my present invention, I have reduced to aminimum the number of parts of the device, and since the same may beformed of castings it will be apparent that devices, in accordance withmy invention, may be very economically manufactured.

It will now be apparent that I have de vised a novel and usefulconstruction of a washerless faucet which embodies the features ofadvantage enumerated as desirable in the statement of the invention andthe above description, and While I have, in the present instance, shownand described preferred embodiments thereof which have been found inpractice to give satisfactory and reliable results, it is to beunderstood that the same are susceptible of modification in variousparticulars without departing from the spirit or scope of the inventionas stted in the claims or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a valve, a casing having an inlet andan outlet, a spindle rotatably mounted in said casing and pressingthrough said outlet, a valve seat in said casing encircling said outletand said spindle, an eccentric fixed to said spindle between said valveseat and said inlet, a valve movably mounted on said eccentric, saidvalve having a cam face formed thereon, an abutment carried by saidcasing between said inlet and said valve seat, said abutment having acam face thereon located in the path of movement of said valve cam face,and means for rotating said spindle to shift said valve into and out ofengagement with said abutment whereby said outlet is opened and closed,said valve engaging said abutment in closed position.

2. In a valve, a casing having an inlet and an outlet, a spindlerotatably mounted in said casing and passing through said outlet, avalve seat removably mounted in said casing and encircling said outletand said spindle, an eccentric fixed to said spindle, a valve having arecess therein adapted to receive said eccentric and provided with a camface, said valve being movably mounted on said eccentric, an abutmentformed on said casing between said inlet and said valve seat, saidabutment having a cam face in the path of movement of said valve camface, and means to operate said spindle to move said valve from oneposition to another, said valve in closed position contacting with saidabutment whereby the said valve is maintained in closed position.
